“Apprentice” champ Bill Rancic has been hired as a “president” in Donald Trump’s real-estate empire – but don’t expect him to be saying, “You’re fired!” to anyone anytime soon.

Rancic will have little authority to go along with his lofty job title – and he’ll be closely watched by experienced minders while he serves as “project manager” of The Donald’s 90-story condo complex while it’s being built in Chicago.

“I’m going to be very much on top of Bill, as will people I have who are extremely professional, who build buildings for a living and they’ve been doing it for a very long time,” Trump told The Post after his reality show’s finale Thursday.

Recent reports say the building – which will be emblazoned with Trump’s name, of course – will have more than 500 condo units and will be the largest structure built in the Windy City since the Sears Tower.

And experts in the building field say Rancic doesn’t have the experience to really be in charge.

“Our project managers on buildings like that have 25-30 years of experience,” said Dan McLean, president of MCL development, a Trump competitor.

“He just doesn’t have the knowledge to be able to make decisions on the actual construction,” he said.

Former Trump project manager Barbara Res said someone who works hard for Trump can go places.

“Donald does a lot of things based on his instinct,” she said. “If you think you could do something, he will let you try to do it.”

Last night on NBC’s “Tonight” show, however, Rancic told Jay Leno he had already “developed a handful of buildings” with a friend in Chicago.

He also had good things to say about his rival finalist Kwame Jackson.

“Kwame is a great guy . . . he is a first-class guy and a tough competitor,” said Rancic. Meanwhile, Jackson has gotten a job offer from another flamboyant billionaire.

High-tech entrepreneur and Dallas Mavericks owner Mark Cuban called the “Apprentice” loser away from his after-show party Thursday to offer him a job overseeing investment portfolios for his company.
